Suppose we draw the shape of a sheep in the plane R2 , and our shape has an area of 4.5 square units. Then we shear our shape by applying the shearing transformation whose matrix is 3 4 1 2       . Determine the area of the sheared sheep. Explain briefly how you arrived at your answer.

Blue fish = 20

Step-by-step explanation:

Let x be the number of blue fish in the aquarium.

The aquarium has 10 more red fish than blue fish.

Number of red fish = x+10

Total number of fished = x + (x+10) = 2x+10

It is given that 60 percent of the fish are red. It means number of red fishes is equal to 60% of total fishes.

Isolated variable terms of left side.

Divide both sides by -0.2.

Therefore, the number of blue fishes is 20.
